Earth fault

Danfoss · VLT Micro Drive FC 51

What does 14 mean?

A discharge (current leakage) from one or more output phases to ground has been detected. This indicates an insulation breakdown in the motor, the motor cables, or potentially the drive's output stage, posing an electrical safety hazard.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Inspect the motor's terminal box, cable glands, and the cable route for any signs of damage, chafing, or contamination.

  2. 4

    If the fault persists after disconnecting the motor, the drive itself may have an internal earth fault, requiring professional service.
